UNITED STATES LOUIS LUCKHOFF, OF FENTQN, OHIO.

FOLDNG SEAT.

Application filed March 5, 1925. cserial No. 13,197.

To all whom t may concern Be it known that I, LOUIS Lucknow, a citizen of the United States, residing at Fenton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Folding Seats; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention aims to provide a rather simple and inexpensive, yet a very desirable form of folding seat which may readily be carried in an appropriate. case, to any7 point at which its use is desirable.

In forming the seat proper, a plurality of pivotally mounted segmental plates are provided, said plates being carried by the upper end of a standard, and as all of these plates could not be advantageously folded downwardly against the standard, it is a. further aim of the invention to provide a unique construction and association of parts whereby a number of the plates are swung downwardly and the others are swung upwardly.

A. still further object is to provide novel means for holding the plates in horizontal position for use.

Yet another aim is the provision of unique pivotal mounting means for the plates.

With the foregoing in view, the invention resides in the novel subject matter herein after described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a side elevation of a seat constructed in accordance with my invention, showing it in readiness for use.

Figure 2 is a view similar to Fig. 1 but illustrating the structure folded for carrying.

Figure 3 is a side elevation partly broken away and in section, illustrating the manner in which the device may be carried in an appropriate case.

Figure 4 is a top plan view.

Figure 5 is a vertical sectional view as indicated by line 5-5 of Fig. 4t.

Figure 6 is a detail plan view with a portion of the device removed, illustrating the manner of pivotally mounting the segmental plates.

Figure 7 is a top plan view of one of the slidable collars which are used in adjusting the plates.

In the drawings above briefly described,

the numeral 1 designates an appropriate standard which may be provided at its lower end with. any desired type of base 2. This basel ispreferably provided with a socket 3 which receives the lower end of the standard 1, either detachably or permanently. In the present showing, the upper end` of the standard 1 is formed with socket et which receives a downwardly projecting boss 5 on a circular head 6, said boss being secured in the socket by any suitable means, such as the screws 7 shown in Fig. 5.

The head 6 is formed of upper and lower sections 8 and 9 secured together by a rivet, bolt or the like l0, said head being provided with circumferentially spaced notches 11 which receive radially disposed lugs 12, said lugs projecting inwardly from a plurality of segmental plates 13 which are adapted to jointly form a horizontal seat. Preferably, these plates are rather thin and their lower sides are reinforced by ribs 14 which connect with the lugs 12. These lugs are provided with transverse oppositely projecting bearing stubs l5 which are received in grooves 16 formed in the inner faces of the head sections 8 and 9. By this construction, the plates 13 are pivotally mounted in an inexpensive manner, yet they will possess the desired stability when in use, and they may be readily swung to and from operative position.

Pivoted at 17 to alternate plates 13 are a plurality of relatively short downwardly converging rods 18, while similar but relatively long rods 18a are pivoted at 17a to the intervening plates. The lower ends of the rods 18 are pivoted at 19 to an upper collar 20 which is slidable along the standard 1, while at 19, the rods 18a are pivoted to a similar collar 20a disposed under the col lar 20. When the seat is extended for use, the collar 20a is supported by a pair of springprojected dogs 21 which are pivoted in appropriate recesses 22 in the standard 1, and the collar 20 then rests upon said collar 20a. When it is desired to fold the device as shown in Fig. 2, the collar 20 is forced upswing `the remainingplates downwardly.A Compact folding of the device is thus effected, so that it may be convenientlyn earried in an appropriate case, such as that indicated at C in Fig. 3.

Preferably, the standard l is provided with at least one longitudinal rib 23, and each of the slidable collars is'formed` with a keyway 24 to engage such rib, thus holding the collars against turning upon the standard and thereby overcoming any possibility of any of the pivots binding. This standard may either be formed of wood or metal, as occasion may demand, and if desired, it may be of tubular formation, for the salie of lightness.

Excellent results are obtainable from the general construction disclosed and such construction is therefore preferably employed. However', within the scope of the invention as claimed, it will be understood that numerous variations may be made.

1. A folding seat comprising a standard, a plurality of segmental plates pivotally connected with the upper end of said standard and adapted to ljointly form a seat, certain of said plates being pivoted for swinging upward and the intervening` plates being pivoted for swinging downwardly and releasable means for holding said plates in horizontal position for use and for permitting swinging thereof in the above-named directions when use of the seat is not required.

2. A folding seat comprising a standard, a plurality of segmental plates pivot-ally connected with the upper end of said standard and adapted to jointly form a seat, rods pivoted to said plates and converging downwardly therefrom, upper and lower collars slidable along said standard, certain of said rods being pivoted to the upper collar to effect upward swinging of certain of said plates, the other rods being pivoted to the lower collar to effect downward swinging of the re- `maining plates, and means for holding the collars in set position on the standard when the plates are horizontally positioned for use.

3. A folding seat comprising a standard, a plurality of segmental plates pivotally connected with the upper end of said standard and adapted to jointly form a seat, rods pivoted to said plates and converging downwardly therefrom, upper and lower collars slidable along said standard, certain of said rods being pivoted to the upper collar to effect upward swinging of certain of said plates, the other rods being pivoted to vthe lower collar to effectV downward swinging of the remaining plates, and means for holding the lower collar against descent when the plates are horizontal for use, the upper collar being then adapted to rest upon said lower collar.

Il. A folding seat comprising a plurality of segmental plates having radially disposed inwardly projecting lugs at their inner ends, said lugs being provided with transverse bearing stubs at opposite sides, a head surrounded by said plates and having notches receiving said lugs, said head being formed of upper and lower sections secured together, said upper and lower sections having in their inner, engaging surfaces, registering grooves receiving said bearing stubs, means for supporting said head, and means for holding said plates in position for use.

In testimony whereof I have hereunto afixed my signature.

LOUIS LUCKHOFF.
